WS Seal Against Coarse Dirt

Perfect to protect bearing units which been used in sea water, dirt and other harsh environments!

The Extreme Bearing WS seal is a wrapping seal, because it is wound around the shaft against the direction of rotation. The WS seal is a secondary seal solution to protect the primary seal in the bearing unit from violence from the outside by, for example, sand and stones and other coarse dirt.

Wound Around the Shaft

The Extreme Bearing WS seal is a wrapping seal, because it is wound around the shaft against the direction of rotation. It is a somewhat simple solution and it takes a bit of space to install it. But once installed this seal can be a perfect addition to protect the seal in the bearing housing against coarse dirt from the outside.

The direction of how the wrap seal is wrapped around the shaft is important. Also, the winding direction has to be against the turning direction so that the dirt is turned out of the labyrinth seal.

  • Cement plants
  • Agricultural equipment
  • Outdoor conveyors
  • Any environment with coarse airborne contaminants

Installation Tips

  1. Wind the seal around the shaft in the direction opposite to shaft rotation
  2. Ensure 3 complete wraps for optimal protection
  3. Position against the bearing housing seal
  4. Verify the seal is tight but not overtightened
  5. Check rotation direction to ensure dirt is expelled outward

The WS wrapping seal provides excellent secondary protection and can significantly extend the life of your primary bearing seals in harsh conditions.
